    摘要: An image sensor includes a pixel array including at least one active pixel and at least one line-optical black (L-OB) pixel arranged in a matrix including first to nth rows and first to mth columns, the pixel array configured to output a pixel signal and a dark-level offset signal in units of columns during a read-out operation in one of the first to nth rows; a row driver configured to output a selection control signal to the first to nth rows; and an analog-to-digital converter (ADC) block configured to digitize the pixel signal and the dark-level offset signal. In the pixel array, a dark-level offset signal is simultaneously output from an L-OB pixel in another row during the read-out operation in one of the first to nth rows. Here, ‘n’ and ‘m’ each denote an integer that is equal to or greater than ‘2’.

    摘要: A clock driver capable of minimizing the ripple of an output signal of a charge pump, and the charge pump including the clock driver are disclosed. The clock driver that generates at least one control clock signal for controlling a pumping circuit, the clock driver includes: a first driver generating a first control clock signal by pulling up a first node, in response to a first reference clock signal and pulling down the first node in response to a second reference clock signal; and a second driver generating a second control clock signal by pulling up a second node in response to the second reference clock signal and pulling down the second node in response to the first reference clock signal; wherein the first driver comprises a first hysteresis controller that generates a first output signal having a time delay in response to the rising transition or the falling transition of the second reference clock signal so that the timing for a pulling down operation of the first node is delayed as compared to the timing for a pulling up operation of the second node.
